In describing my invention, I shall refer' to the drawing in which similar reference characters designate corresponding parts throughout the severalviews and inwhich the numeral 1 designates a casing which is` formed `of two substantially rectangular plates2iand3 lwhich are superposed, and have atV their opposite end `edges each a laterally projecting flange 4 or 5 which form end walls for the casing: The end flange 5 which projects upwardly `from the bottom plate which is designated bythe numeral 3 extends a predetermined distance above the top plate 2 tocorma guide flangel 6, the purpose of whicli'is obvious indevicesof this character. The plates 2and'3 lof the? casing are connected atf-theirfsides by psub` stantially U.-shaped'bars ;7 which-havetheir rrecess in the` door, and the latch plate lo'p'enarm portionsfsecured lto 'thevlowerlsurface ofl the top plate 2 and the uppery surface of the? bottom plate 3, adjacentflthe' edges ofV the same respectively. These I connections are i o j n riveted as designated byf'the numeralrv 8; Inthe accompanyinggdrawing; j A

outwardly through the same, for a. purposekscrews l2 and 13 Aprojectthrough thewalla offthee casing, and aregprovded with. slots-j.r

15 therein to receive a screw driver, or any other tool whereby the screws may be ro tated.

Positioned on the screws 12 and llwithin the casing are nut members 16 whichproject inwardly, and have portions 17 thereof directly between the slots 9 in the -upper and lower plates of the casing. These pon tions 17 of the nut members are recessed as shown at 18, and are adapted to receive the spurs 11' which have forked or split lower ends 19 disposed within these recesses. These spurs 11 are adjustably held in position by means of set' screws Z0 which project through the split ends of the spurs, and are positioned in apertures 21 in the recesses, The portions 17 of the nut member y1G are provided with these spurs at thetop and bottom of the same, so that the spurs will project in pairs through the slots in the top and bottom plates. These nut members 16 are Jthreaded and are operatively engaged by the screws 12 and 13, so that upon rotation of the screws in either direction, the nut members and spurs will be moved along the slots accordingly. By this means the spurs may be adjusted according` to the different measurements desired.

Atthe end wall.4 of the casing 1 is positioned another short length screw 22 which has' one end swiveled in and projecting through said end wall, while its opposite end is positioned in the outer side of the bearing block 14. The projecting end ot lthe screw 22 is provided with a slot, so that it may be engaged lby a screw driver or any other tool to rotate the same. Positioned on, the swiveled screw 22 is an inwardly extending nut member; which is operatively engaged therewith, and the inner end of said member is bent parallel with said screw as shown at 24 and projects through an opening 25 in the wall 4 of the casing. PosiY tioned on the extremity of the projecting portion 24 of this member is a spur 26. It will be obvious from this arrangement that upon rotation of the screw Z2 the nut member 23 will be moved accordingly, and the spur 26 will be adjusted toward and from the end wall of the casing. This spur 26 as well as the 'spurs 11 which move within the slots 9, are detachably connected, so that they may be easily removed and replaced when the original spur is worn.-

From the above described construction and arrangement of parts it will be seen that I have provided an extremely simple gage of this character which is adapted for quickly and accurately locating in a door the exact points at which to cut the openings for the lock. This gage is also adapted to locate the points at which to cut the opening for the adjacent face plate vin the frame, and also the width and depth of the cuts for the hinges. When the gage is used to determine the correct width of hinge leaves., as shown in Figs. 10 and 11 ot' the drawings, the same engages the door A as clearly shown in Fig. 10, with the flange positioned against one side of the door, and one of the spurs correctly adjusted so as to score the edge of said door according to the width of the hinge leaf. In Fig. 11, the gage is pol sitioned in the door amb B in such a manner that the flange will be within the recess portion or the jamb, and it will be obvious that there will be a slight difference between the two widths, owing to the projecting flange, this width being sutiicient to prevent the door from binding. It will be understood that the spurs which determine the width of the leaf are adjusted the same for engaging the door and jamb; consequently the slight difference is caused by the flange.

In Fig..12, the operation and use of the projecting spur 2G at one end of the same is illustrated. This spur is adjusted to determine the correct depth of the cut to re.- ceive the hinge leaf, and the same is engaged with the door jamb B as clearly shown in the figure, but it is obvious that it can equally as well engage the door A to determine the correct depth to be cut away to form the hinge receiving recess.

Figs. 13 and 14 are diagrammatic views showing the use of the gage at the opposite side of the door, Fig. 13 showing the gage in position to determine the width of the lock receiving recess, while in Fig. 14 the gage is positioned to determine the width of the latch plate opening. When used to gage the latch receiving recess the gage is positioned against the door A with the lange engaging one side of the same, and the spurs correctly adjusted to the desired width. The gage is then operated to score the edge of the door in parallel lines the required distance apart. This same operation is repeated in applying the device to the door j amb B, only in this instance the flange 1s positioned within the recess, thus creating a slight difference in the positioning of the gage and lines scored thereby which will give a sufficient play so as to prevent the door from binding when in operation. The various means of adjusting the spurs which project through the slots in the top and bottom plates of the casing, and the spurs which project from one end of the same have been hereinbefore described, and the method of operating the same isobvious.

I claim:

1. A d evice of the class described comprising a casing having a slot in one side thereof, a screw swiveled in said casing adjacent one side ofthe slot, a nut member on said screw having one flat side thereof extending transversely across the slot, a spur detachably connected with the portion of the member l said slot, onekend of said screwr being adapted for engagement with operating tools.
